Newlywed Kim Kardashian's sex tape (good 39-minutes long) with her former singer boyfriend Ray J has been valued at more than £18 million by its owners.
The tape features Kim's intimate act with the R'n'B singer in a hotel room.
Vivid Entertainment has the rights to the tape as of now and has been approached by a Tennessee law firm representing a bidder who is rumoured to be related to Kardashian. The letter says: "We would purchase any other footage you may have control of that involves Ms Kardashian," reported The Sun.
Vivid boss Steve Hirsch told the newspaper: "Based on its long term value, it looks like £18million would be a starting point for a discussion on all of the rights. I have no idea who is behind this offer but if it's Kim, I have a tremendous amount of respect for her. She has my number and can call me any time."
The clip has become a rage online especially after her marriage to basketball player Kris Humphries.
Kim, who received a £3million pay-off over the tape, said earlier this year: "There's embarrassment and shame."
